"Unable to turn off 'Do Not Disturb' on my iPhone 14 Pro: My 'Do Not Disturb' will not turn off on my IPhone 14Pro - I have turned my Focus off but this feature will not turn off so of course I have missed my calls all day - I have never had this happen before - turned my phone off and back on - still there - I have never used this feature before before!!!"

Troubleshooting Do not Disturb:
A. Doublecheck your settings: Use Notifications on your iPhone, iPad, and iPod touch - Apple Support
B. Check what is Allowed: Notifications: Use Do Not Disturb on your iPhone, iPad, and iPod touch - Apple Support
C. Update your iPhone:
When's the last time your updated your iPhone? iOS 18.3.2 is the latest available update. So, try updating to it. If you cannot not do so on the iPhone itself, then try using a computer. Go here: Update your iPhone Using a Computer - User Tip. If any updates are available, they will install, sure enough.
IMPORTANT: If you have an option to update, however, then be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the update.
